“…The level of Ca in the blood of Bali cattle reared in rice fields were also low due to consuming feed with low Ca (Pujiastari et al, 2015). Phosphorus is essential in bone mineralization and reproduction (Zhou et al, 2021). In this study, the availability of P in extensive rearing management was higher than intensive and semi-intensive.…”

Livestock-oil palm plantations integration system is intended to improve farming efficiency, where agriculture not only plays a role as the primary producer of food but also as a producer of feed, fertilizer, energy, and other bioproducts, leading to a sustainable agricultural system. Smallholder farmers in Indonesia integrated Bali cattle and oil palm with extensive, semiintensive, and intensive management systems. This study evaluated the integrated system of oil palm and Bali cattle under different management systems regarding the characteristics of smallholder farmers, nutritional status, and weight gain of Bali cattle on smallholder farms. The study was conducted in the Regency of Central Bangka, Bangka Islands, Indonesia. The study included 108 Bali cattle grouped as calves, young, and adults. The observed variables included smallholder farmer characteristics, feed nutrients, feed nutrient consumption (Dry Matter (DM), protein, Ca, and P), feed digestibility, and body weight gain. A Randomized Block Design and analysis of variance for the obtained data were used in this experiment. Smallholder farmers implementing the integration of livestock-oil palm in Central Bangka Regency were dominated by inexperienced novice farmers. The majority of the farmer choose semi-intensive rearing management as this system produces compost as a by-product. The semi-intensive system also provides better feed quality for Bali cattle. Therefore, DM consumption in the semi-intensive system was higher than in other systems, especially in young bulls, heifers, and male and female calves (P<0.05). Thus, Bali cattle in the semi-intensive system had higher average daily gain than those in the intensive or extensive system. Therefore, it can be concluded that the semi-intensive management system is the best model in the Bali cattle-oil palm integration system in the rural dryland area, in accordance with nutritional status and the characteristics of smallholder farmers in Indonesia

“…The low Ca consumption was due to the low Ca content in forage in oil palm plantation areas which was consumed in extensive rearing management (Table 4). Additional mineral intake is needed to meet the Ca requirement (Zhou et al, 2021). The highest P consumption in cattle was shown by extensive rearing management.…”

“…Since yaks are seasonal breeders with a high natural conception rate, the fertility of a yak herd is primarily influenced by the percentage of yak cows that return to estrus in the year of calving. Research conducted at Sichuan revealed that 78% of female herds became pregnant following their first service, 15% following the second, and 7% following the third or more ( 79 ). Moreover, puberty onset is significantly influenced by nutritional conditions and the rate of live weight increase, with faster-growing yak heifers experiencing it earlier ( 79 ).…”

Yaks play an important role in the livelihood of the people of the Qinghai-Tibet Plateau (QTP) and contribute significantly to the economy of the different countries in the region. Yaks are commonly raised at high altitudes of ~ 3,000–5,400 m above sea level. They provide many important products, namely, milk, meat, fur, and manure, as well as social status, etc. Yaks were domesticated from wild yaks and are present in the remote mountains of the QTP region. In the summer season, when a higher quantity of pasture is available in the mountain region, yaks use their long tongues to graze the pasture and spend ~ 30–80% of their daytime grazing. The remaining time is spent walking, resting, and doing other activities. In the winter season, due to heavy snowfall in the mountains, pasture is scarce, and yaks face feeding issues due to pasture scarcity. Hence, the normal body weight of yaks is affected and growth retardation occurs, which consequently affects their production performance. In this review article, we have discussed the domestication of yaks, the feeding pattern of yaks, the difference between the normal and growth-retarded yaks, and also their microbial community and their influences. In addition, blood biochemistry, the compositions of the yaks' milk and meat, and reproduction are reported herein. Evidence suggested that yaks play an important role in the daily life of the people living on the QTP, who consume milk, meat, fur, use manure for fuel and land fertilizer purposes, and use the animals for transportation. Yaks' close association with the people's well-being and livelihood has been significant.

“…O bovino tem capacidade de mobilizar fósforo dos ossos (e dos tecidos moles) quando a dieta é inadequada (30). Os microrganismos do rúmen parecem ser menos sensíveis que o hospedeiro à deficiência de P. Esta resistência devese provavelmente à eficiente reciclagem do elemento através da saliva e aos requisitos relativamente baixos dos microrganismos, embora, tanto reduções na síntese de proteína microbiana, como ineficiente degradação da fibra, tenham sido descritas pela deficiência deste elemento (31,32).…”

A alimentação é o fator que mais onera um sistema de produção animal. Assim, a utilização de diferentes estratégias de alimentação dos animais ainda é o grande desafio da nutrição animal, principalmente, levando-se em consideração as exigências nutricionais de diferentes categorias de ruminantes, em especial bovinos. A sazonalidade é a principal causa da baixa produção bovina nos trópicos, promovendo inadequação no atendimento das exigências nutricionais dos animais principalmente em minerais e vitaminas. Estudos que abordam o efeito e a importância de vitaminas e minerais na nutrição bovina são escassos. Nesse sentido, objetivou-se com esta revisão trazer informações acerca de vitaminas e minerais na nutrição de bovinos em pastejo.
